SAFETY AND HANDLING
• Read and fully understand ALL manufacturer’s instructions before 
beginning. Failure to follow proper installation instructions 
may result in the denial of warranty claims for operational or 
performanceproblems.
• Use safe lifting techniques.
• Wear protective gear (e.g. safety glasses, gloves, ear protection, etc.).
• Operate hand/power tools safely and follow manufacturer’s 
operatinginstructions.
• Heed material manufacturer’s handling and application instructions.
• Store doors in a dry, well-ventilated building and on a at and 
levelsurface.
• Do not subject interior doors to extremes of heat and/or humidity. 
Prolonged exposure may cause damage. Buildings where humidity 
and temperature are controlled provide the best storage facilities 
(recommended conditions 30%-50% Relative Humidity and 50°F 
to90°F).
• Do not install doors in buildings that have wet plaster or cement 
unless they have been properly nished. Do not store doors in 
buildings with excessive moisture content - HVAC systems should 
be operating and balanced. Avoid sudden changes such as forced 
heat to dry out a building. Doors should not be delivered to the job 
site or installed until concrete oors, foundation, plaster or drywall 
arecured.
• Doors should always be handled with clean hands or while wearing 
clean gloves. 
• Doors should be lifted and carried when being moved, not dragged 
across one another. 
• Finish all six sides (both sides and all four edges) of the door 
slab, including cutouts for hardware. Failure to nish all six sides 
may result in the denial of warranty claims for operational or 
performanceproblems.
• If disturbing existing paint, take proper precautions if lead paint 
is suspected (commonly used before 1979). Your regional EPA 
(www.epa.gov/lead) or Consumer Product Safety Commission ofces 
provide information regarding regulations and lead protection.
• WARNING: Drilling, sawing, sanding or machining wood products 
generates wood dust, a substance known to the State of California to 
cause cancer. Use a respirator or other safeguards to avoid inhaling 
wood dust.
IF INJURY OCCURS, IMMEDIATELY SEEK MEDICAL ATTENTION!
